Specification of Letters Patent.

Patented July 24, 1906.

Application filed January 23, 1904. Serial No. 190,360.

las, in the 'county of Dallas and State of Texas, have invented new and useful Improvements in Coffee-Pots, of which the folowmg is a specification.

This invention relates to coffee-pots or the like; and the primary object of the same is to provide a simple and effective device of this class having means which also serves as a handle for transferring the contents of the lower part of the body of the coffee-pot or the like to the upper portion thereof over a receptacle for holding coffee, tea, or other material to permit the elevated contents to peroolate through the coee or substance in the tacle and pro erly maintain the strength of t e beverage a apted to be dispensed from the pot.

A further object -of the invention is to provide a coffee-pot or other culinary device with means for elevating the lower portion of the contents thereof to the upper part of the pot or device having an organization of sepacleaning and other purposes.

A further object of the invention is toreduce the parts necessary to perform the operation desired to a minimum and also to provide a coiee-pot or analogous device with mechanism for elevating the contents thereof from the bottom of the pot to the upper part .of the latter without modifying the structure of said body.

A further object of the invention is to include in the elevating attachment such organization of valve elements that the heated liquid will be permitted to run back to the lower part of the body aftercessation of the pumplng o eration, and thereby avoid heating the han e embodying the attachments.

The invention consists in the construction and arrangement of the several parts, which will be more fully hereinafter set forth.

In the drawings, Figure l is a side elevai tion of acoifee-pot, shown broken away in part and illustrating the handle mainly in section and embodying the improved attachments. Fig. 2 is a horizontal section on the line 2 2, Fig. 1, with the lower valve removed. Fig. 3 is a side elevation of the u per portion of a coHee-pot, broken away an illustrating a holding-receptacle therein. N

Similar numerals of reference are employed to indicate corresponding parts in the views.

The numeral 1 designates a coifee-pot of any suitable dimensions having a closing lid or cover 2 anda pouring-spout 3, with a hinged cap 4 to preserve the strength and aroma of the contents ofthe body of the pot, The upper part of the pot-body has an inwardly-struck seat-corrugation 5, which supports a removable receptacle 6, comprising, preferably, an upper ring 7 with a fabric body 8 of suitable dimensions. The receptacleis fully open at its upper extremity and gradually reduces in diametrical extent toward its lower terminal or is practically of' inverted conicalcontour. Thereeeptacleisada tedto receive coffee,tea, or other material, an thereon is delivered hot water or the contents in the lower part of the pot-body similar tothe operation of making coffee or other beverage in what is known as a drip-pot.

The essential part of the attachment consists of a pumping means arranged as a handle and comprises a lower reduced pipe or conduit 9, with a gradually-curved terminal 10, connecting with the bottom of the potbody. The upper end of the pipe or conduit 9 has an enlargement 1 l thereon formed with a valve-seat 12, to which the door of the pipe or conduit leads. The valve-seat 412 is grooved, as at 12, to permit the um to drain or allow the liquid that may e a ove the valve 20 and the plunger, which willbe 12. Projecting from the enlargementll is a connecting-brace 15, which is attached to the pot-body. The handle also includes an upper pump barrel or tube 16 of material greater diameter than the pipe or conduit 9 and having its lower end removably inserted in the flange 13. The barrel or tube 16 has a surrounding heat-non-condueting covering 16, preferably of wood, and a removable screw-threaded cap 16". Between the lower end of the barrel or tube 16 and the shoulder 14 a perforate plate 17 is interposed and has an enlarged central 'opening 18, through which movably projects the stem 19 of a gravitating valve 20, the latter coperatin with the seat 12. On the upper end of t e cap IIO 16b of the barrel or tube 16 is a stuffing-box 21 of suitable 'construction, and movable centrally therethrough is a piston-rod 22, detachably secured at its lower end to the head` 23 of a piston-yoke 24, having the lower terminals of its arms removably secured to a iston 25, a loose leather or fiber packing 26 eing held between the ends of the yoke-arms and the head to establish a tight joint betweenthe said head and the inner surface of the barrel or tube 16,. Extending vertically through the center of the head 2 5 is an opening 27, leading to a valve-seat` 28, formed in the center of the upper end ofthe head, and movably extending through said opening is a stem 29, having on its upper endl a valve 30, movable in relation to the seat 28. The upp er end of the piston-rod 22 has a ball or other suitable grip device 31 thereon for conveni'ence in vertically reciprocating the piston-head. Attached to the upper extremity of the barrel or pipe l'is a horizontal outlet conduit or pipe 32, which extends through an openin 1n the pot-body and has its inner terminal ownwardly curved to form a delivery-spout 33, which is disposed over the center ofthe receptacle 6.

The receptacle 6 having been dis vosed in the upper part of the pot, coffee or ot er analogous material is placed therein and boiling water oured thereover. The water percolates t ough the coffee and the fabric 8, forming the main body of lthe receptacle, and falls into the lower art of the ot-body. This operation, may e successive y carried on until a large quantity of liquid is contained in the pot below the receptacle 6. It will be understoodthat the required strength and advantageous aroma of the contents of the pot-body below the receptacle 6 will be materially increased by repeatedly causing the same to iiow through the contents ofthe said receptacle 6. For this pur ose the pumping attachment embodied in tiie handle is used, and by drawing upwardly onthe iston-rod 22 and 'elevating the piston-hea -25 the valve 20 will be raised from its seat, and:

the liquid in the lower part of the pot-body Will be drawn outwardly throughthe pipe or conduit 9 and pass through the perforate plate 17 into the pump barrel or tube 16 in cpllantity proportionate to the upstroke of t e piston-head. On the downstroke of the said-head the valve 20 will be forced from itsl seat and the valve 30 opened or.- elevated', thereby allowing the li uid below the pistonhead to flow through t e latter into the upper part of the barrel or tube 16. Successive operations ofthe piston-rod and its head will cause the liquid in the lower portion of the pot-body to be elevated and pass through the outflow conduit or pipe 32 andbe delivered over the contents of the receptacle 6. After the pumping operation is completed the piston-rod may be forceddownwardly to latter.

avoid material projection thereof, and what portion of the heated liquid that may remain in the pipe or conduit 9 will flow back into the body of the pot and prevent heating the handle ofthe latter embodying the pum Sattachment. In the event that there shou d be any tendency toward sticking of the valves the projecting stems will contact and force the valve 20 down to its seat and raise the valve 30. At any time desired the parts may be separated for cleaning, and changes in the dimensions and proportions of the same may alsoA be adopted in consonance with the variations of the sizes of pots. The perforate plate 1`7 serves as an efficient support for the valve 20 and its stem 19, so that said valve will always be held in centrall position.

One of the main advantages of the im-- ipoved construction is .that hot water may be st placed in the lower part of the Otebod'y l and the lid or cover 2' applied over t e upper end of the latter. The water may then be elevated to the receptacle 6 and percolated through the coffee or other material in thearoma of the coffee or other material'- willbe lpreserved by reason ofthe inclosure of`1 the 'water, and all vapors that may be formed are 'held' within the pot-body. Furthermore-, a .more extended surface to receive the waterv is provided by the form of receptacle` before explained, and', furthermore, the ordinary pot-body may be used without changing the Vstructure of the same, thereby reducing the cost of manufacture.

Havin thus fully described the invention, what is c aimed as new is- A pot comprising, in combination, a body having a pouring-spout and a cover., a receptacle removably-mounted in the upper part of the body below the cover, a hollow handle disposedl externally of and parallel withl the bo of the pot and threaded' at its lower end, an eduction-pi e communicatingy at its lower end with the ody of the pot andenlarged at its upper'end to form a valve-chamber, said valve-chamber having a shoulder- By this means the full strength' or IOO IIO

and a threaded ortion to engage the lower: y

threaded end o the handle', a perforated guide-plate clamped'against said shoulder by the handle, ava ve controlling the passage in the eduction-pipe and provided with a stem slidable in said guide-plate, a pipe extending laterally from; the'u per endl ofthe handle and rejecting throug the wall=of the pot below t ve cover and'forming acombined2 induction connection and stay r the top of of the handle, a valve-pump piston in thehandle, a stemconnected to said piston and extending outwardly through the upper end of the handle and rovidedwith ahandhold'; whereby the tubu ar handle forms a direct connection between the eductionandinductionpipes andserfves additionallyas a-pump- ISO o linder, the stem ofthe valve in the valvec amber of the eduotion-ppe being so arra ed as to be engaged by the pump-piston at t e limit of the downward movement of 5 the latter to positively close said valve and prevent it from stoking, substantially as described.
